South park makes fun of everyone and everything. I haven't watched southpark in years but I'm assuming they even probably made an episode about reddit users.

They have yet to make fun of Reddit, but they pretty much go after the most absurd shit that people are complaining about. They have been ripping on Trump through Mr Garrison for 3 seasons now, they ripped on Bruce Jenner running someone over, PC culture, SJW's, recently they made fun of white people who renovate houses on TV, BLM last season in an episode called Token's Life Matters. Doesn't matter which side of the coin you are on, you are a target.
